' To all whom it may concern:

Be it known. that I, OSCAR K. SLETTO, of Bend, Crook county, Oregon, have invented certain newand useful Improvements in srrShock and Hay Loaders, of .which the fol :wlowing is a specification.

= 'I-heobject of my-invention is to provide aload-ing apparatus designedforuse with ----.-an automobile chassis. i .A further object is to provide a'machlne of 'wcompact=construction by means of which:

the bundles or shocks or, if .desired,--loose uglrain or ha can be gathered up and deposated in a suitable receptacle. 1 The invention consists generally in an im- 1 proved 'pick-up"-mechan1sm comprising a wrevolving drum and aseries of pick-up.fingers mounted therein, with means for alternately'projectingv said fingers beyond thego'periphery of the'idrum and withdrawlng them withinlthe periphery-of the drum.

Further the inventlon consists in various details of construction for effecting the de- -sired movement of-- the pick-up fingers, all

as'hereinafter described and particularlypointed out in the claims.

In the accompanying drawings forming part of this speoification', Figure 1 is a sideelevation of a shock and hay loaderembody- 'ing my invention. Fig. 2 1s a similar view Y of the opposite side of the machine, showing the rack in its dumping position, Fig. 3 is a front elevation, Fig. 4.- IS a transverse, sectional view through the pick-up frame, Fig.

5 is a detail sectional view illustratingthe :.mannen ofmounting the pick-up fingers in thewdrum, Fig. 6 is a similar view, illustrating the'-stop-device used in connection with-1thelspringwhich :aotuates the pick-up air-fingers.

. 1=Ii1 the drawing, 2 represents a'fi-ame having carrying wheels 3 and 4: and a-source ofs'motiv'e power consisting preferably, in

- :this case of a gas engineamounted con-the- -forward portion of the-frame under a hood .5 and having a driving connection with a shaft 6 from which the rear axle is driven from a sprocket chain 7 in the usual way.-

A gear 8 is mounted on the shaft 6 and meshes with a gear 9 on a shaft 10-, from wvhich a driving belt 11- extends forwardly to a. shaft 12which supports the lower por- "tion of the elevating belt or apron 13 that is arrangedwithin an inclined frame 14-at the upper end of which a shaft-l5 supports the :upper portion of the carrier or apron and an overhanginghood- 16. A rack or receptacle 17 is pivotallysupported at 18 .abovethe rear axle and is capable of tilting vrearwardly to discharge its load.

The elevating. apron overhangsthe forward :portionof the rack, so that the bundles or loose material brought. up by. the elevator will be. discharged into. the 'rack, the operation being continued until the rack is filled. The

rookie held against premature tilting by a hook 19 whichengages theloop 20 onthe rack and holds it in its normally-horizontal position.

I In front of the. frame is a drum .21,mount1 -ed on a shaft 22 that isjournaled inhangem 23 "which. are,carried by the. shaft 12. Arms 24 aremonnted on the hangers 23 and project upwardly: abovethe .shaft, 12 and springs 25 are attached to-saidarms and to .the frame of the machine and. yieldingly support the drum, allowing it to swing back and forth, toward or from the ground line. A cable 26 is attached tothe arms 24 and extends hack to a shaft 27,. the movement of .The pick-up-devicewhich forms-the essential feature of my invention includes. the

. drum 21, heretofore referred to,.and a series ofshafts 34 extending lengthwise within the drum from end to.endand arranged a suitable distance apart aroundthe periphcry of the drum. Upon these shafts a; series of arms-35 are looselymounted, eacl'moarrying acurved pick-up finger 36'wliioh-projects-through.anopening 37 in the wall of .the drum. A collar'- 38 is-seoured on-t-he shaft 34: contiguous to each .arm 35 and has a-finger 39 projecting-over the arm 35. A

a spring 40 is coiled around the shaft 34-and is attached at one end to the collar 38 and at itsother end to the-arm35. This const-ruction-allowr each finger toswin within the periphery of the drum .indepen ently of all --the .ot-her fingers, and when a shaft is. rocked in its bearings, all the fingers supported on i that shaft will be retracted within the peing anti-friction power,

having pick-up I Within the drum riphery of the drum simultaneously through the engagement of the fingers 39 with the arms.

For the purpose of rockin withdraw or project provide gear segments 41 secured to the shafts and meshing with similar segments 42 which are pivoted on spiders 43 provided at the ends of the drum. The gear segments 42 have arms A thereon supportwheels 45 which travel in a cam track 46 as the drum revolves, said track being so arranged that the pick-up fingers will be projected at the proper moment to pick up a bundle of loose grain or hay from the ground and will be retracted just before the fingers reach the elevating belt to which the bundles,

the shafts to or loose rain or hay, are delivered. The

pick-up ngers are also capable of independent projection or retraction,'so that on uneven ground or in case of striking a stone or other obstruction, a finger may wlthdraw within the periphery of the drum until the obstruction is passed. The fingers will thus clear-themselves with each revolution of the drum and will also automatically disengage themselves from any foreign material or obstruction which may be encountered by the drum in its revolution. The drum may be revolved atany suitable speed .but is preferably operated throu h a driving connection with a sprocket 46 rom the shaft 12.

The material having been gathered up may be conveyed rapi ly to a distant point andk then discharged by the tilting of the rac The machine being self contained in its can be moved rapidly from place to place and being composed of but few parts of simple construction can be easily mounted on the chassis of an automobile without any material modification in the driving connections or the locationof the source of power. Y

In various ways thedet-ails of construction mayv be modified without departing from the spirit of my invention.

I claim as my invention 1. In a machine of the class described a wheeled frame, an elevator mounted thereon, a pick-up device comprising a revolv-' ing drum, a series of shafts journaled therein and extending from end to end thereof, gear segments secured on said shafts and fingers arranged to project out of the peripheryof said drum and capable of retraction within the periphery of said drum,.piv.oted gear segments arranged to mesh with said 'first named segments, arms carried by said second named gear segments, antl-frlotlon rollers mounted on said arms the pic z-up fingers, I-

' ing said drum in a direction opposite 1,0eaass and a cam track in which said anti-friction rollers, travel, said track being adapted to operate said gear segments to rock said shafts and retract said pick-up fingers within the periphery of said drum at a predetermined point in its revolution.

2. In a machine of the class described a wheeled frame, an elevator mounted on said frame, a pick-u device comprising a revolving drum, a series of shafts journaled therein, gear segments secured to said shaft and having pick-up fingers projecting outside of the periphery of said drum and mounted to be retracted within the periphery of said drum, arms having teeth meshing with said gear segments, anti-friction rollers mounted on said arms, a cam track in which said anti-friction rollers travel, said cam track being adapted to operate said arms to rock said shafts and retract said pick-up fingers within the periphery of said drum at a predetermined point in its revolution.
